I had to use an old two sided gun tap to complete the tapping of 8 countersunk holes. The mailed tap could not even start the hot roll 1/4 thick steel.
Perhaps it’ll work with aluminum.
Bose Frames Rondo, Certified Refurbished

The frame isn't ready for the public yet and it needs some improvements before final release. Dr. Bose would not have let it through.
I've tried everything to get the volume varied by rotating my head and pressing the little button as the instructions suggest.
I'm still puzzled.
The batteries wear out too quickly and that is an annoyance.
Of course the sound is decent yet it's not fantastic. It's a simple acoustical issue which can be improved through better amplification and equalization.
